Re: Recovering Bricked CFs

I once "bricked" one by accidentally flashing a wrong binary to the drone (not sure if nrf or cf). I could not get it back to work with the client or normal flashing but had to reflash the bootloader, i think using the debugger interface. my script i created back then reads: echo "Mak...

Re: PositionHlCommander Localization system

Sorry for bringin this old thread up. I used to set an initial state estimate according to steps 1 and 2 as mentioned by kristoffer. ... If you want to start your CF at some position that is not the origin the correct procedure would be: 1. Let the position estimator know where the CF is located by ...

[SOLVED] using cflib in WSL2

[Not completely sure if this is the right Sub-Forum] I am trying to setup a development environment using WSL2 under windows 10. Building and flashing works with the current make files using windows' python. As I have to use linux dependent things to connect to my swarm (a.o. ROS) it would be nice t...

Setting parameters when autonomous / set kalman state

We are working on an autonomous swarm and I had some trouble where drones seem to hang when certain commands where issued on the drone. Whenever I wanted to debug via radio / usb connection and the console prints, everything was fine. So this took me a while... ;) Turns out I was writing parameters ...

Re: Communication between Crazyflies

Am also working on a relaying protocoll.
It's basically done (the transport layer at least) but needs some more love and some preperation to make it public.
Hope I find the time (and get a go) during the next weeks

P2P broadcast package size watchdog when also connected to crtp

Hi, I implemented some P2P swarm protocoll and realised after quite a while that when I use a data size of P2P_MAX_DATA_SIZE (60), the propability of the watchdog kicking in is quite high. Especially when als connectetd to the client via crtp-radio. Everything works fine now if I lower the data size...

P2P Unicast Routing etc

Hi, I have seen there is a P2P broadcast (that I am able to use). Most times a development towards P2P unicast is mentioned. Is there an update on the current state, or a development branch to this? I probably need some P2P including routing/forwarding acknowledging, but only would like to start fro...

Re: Working with multiple drones

Hi kristoffer, this should help a bit with (1), thanks. - Is there also a way I can set the crazyfly into bootloader mode with a command (python? local headers on the drone?)? - Can I enumerate the addresses automatically (via python/firmware)? Do the drones have other internal IDs I can access for ...

Working with multiple drones

Hi, I am trying to implement a swarm, therefore i have some practical questions regarding deploying and instance independent firmware: 1) Is there a way to simultaneously update multiple drones? (nrf and firmware), (via radio? via cable/pins?) 2) I need some automatic enumeration / ID. In the firmwa...
